METHOD OF REGENERATION OF PLATINUM GROUP METALS FROM TOUCHSTONES AFTER TESTING CONTROL OPERATIONS Russian patent published in 1994 - IPC

Abstract RU 2021383 C1

FIELD: metal regeneration. SUBSTANCE: metals are subjected for electrochemical dissolving in the solution containing 10-479 g/l hydrochloric acid at the alternating current density 10-5000A/m2. Touchstones made of silicon-containing conductive material are used. Metal extraction is carried out by electrolysis using cathode made of porous conductive material. EFFECT: improved method of regeneration. 1 tbl
